I attached a picture of the diagram associated with this question.
Now,
When we check the vertical components of the tension in the rope, we will find that we have two equal components acting upwards.
These two components support the weight and each of them has a value of TcosΘ
The net force acting on the body is zero.
Fnet=Force of tension acting upwards-Force due to weight acting downwards
0 = 2TcosΘ -W
W = 2TcosΘ
T = W / 2cosΘ

Answer:
The workdone is
Explanation:
From the question we are told that
The height of the cylinder is
The face Area is
The density of the cylinder is
Where is the density of freshwater which has a constant value
Now
Let the final height of the device under the water be
Let the initial volume underwater be
Let the initial height under water be
Let the final volume under water be
According to the rule of floatation
The weight of the cylinder = Upward thrust
This is mathematically represented as
So
=>
Now the work done is mathematically represented as
Substituting values
